"Zenith" Headless E-commerce

Crafting a sub-second, app-like shopping experience.

Project Overview

  • Client: Confidential Fashion Brand (NDA)
  • Role: Lead Developer & Architect
  • Duration: 3 Months

The Challenge

The client's old e-commerce site was slow (4.8s load time), had a 60% mobile bounce rate, and was difficult to update. They needed a modern solution that was blazing fast and flexible.

My Role & Solution

I architected and built a new headless solution from the ground up, following Jamstack principles. I decoupled the frontend (what the user sees) from the backend (the commerce logic), communicating between them with APIs. This allowed for instant page loads and a fluid, app-like feel.

I used Next.js for Server-Side Rendering (SSR) and Static Site Generation (SSG), which pre-builds pages for incredible speed and SEO benefits. The backend was managed by a headless CMS (Sanity.io) and the Shopify API, giving the marketing team the flexibility to update content without needing a developer.
